Multiproject dependencies not accurate for project.compileClasspathElements when run from root project

Details

Description

In a plugin I wrote (jspc), needs the dependency jars. It asks for this with the request for the project.compileClasspathElements. In a multiproject environment, when each project is built individually, it seems correct. Example (when run with -X ina subproject dir) showing classpath:

/Users/mbp/.m2/repository/javax/servlet/jsp-api/2.0/jsp-api-2.0.jar
/Users/mbp/.m2/repository/taglibs/standard/1.1.2/standard-1.1.2.jar
/Users/mbp/.m2/repository/javax/servlet/servlet-api/2.4/servlet-api-2.4.jar
/Users/mbp/.m2/repository/tldtestapp/testexttld/1/testexttld-1.jar <-----------------NOTICE HERE - THIS IS AN ARTIFACT FROM ANOTHER SUBPROJECT
/Users/mbp/.m2/repository/javax/servlet/jstl/1.1.2/jstl-1.1.2.jar]

When it is run from the Top level/Root project...here is the output:

Users/mbp/.m2/repository/javax/servlet/jsp-api/2.0/jsp-api-2.0.jar
/Users/mbp/.m2/repository/javax/servlet/servlet-api/2.4/servlet-api-2.4.jar
/Users/mbp/.m2/repository/taglibs/standard/1.1.2/standard-1.1.2.jar
/Users/mbp/Desktop/jsp-example/TestTldProject/target/classes <----------------NOTICE - THE JAR IS NOT BEING ASKED FOR, BUT A CLASSES DIR INSTEAD
/Users/mbp/.m2/repository/javax/servlet/jstl/1.1.2/jstl-1.1.2.jar]

The second project has a dependency on the testexttld-1.jar because it contains tag libs which must be wrapped in a jar. When run from a top level, it uses the other project's classes directory instead of the JAR artifact. WIth JSPC and taglibs, this makes it so it cannot work. If I have a dependency on a jar, that jar should be the dependency as expected and not a classes directory. For full explanation and example see here:
